1. Students will be able to describe how light and electron microscopes function as well as the use of the Metric system when using a microscope. a. Microscopes enable biologists to examine the details of cell structure and to understand how organisms function. b. Scientists use the metric system when measuring objects. c. Light microscopes have a low magnification and can be used to examine living cells. d. Electron microscopes have a high magnification but cannot be used to examine living cells. e. The Scanning Tunneling Microscope uses a computer to generate a three dimensional image of an object. 2. Students will be able to explain the major features of a cell in regards to prokaryotes vs eukaryotes and the cell theory. a. The cell theory has three parts. (Click Here For Video!) b. Small cells function better than large cells due to having a higher surface area to volume ratio compared to large cells. c. All cells have a cell membrane, cytoplasm, ribosome’s and DNA. d. Prokaryotes lack internal compartments. (Click Here For Video!) e. Eukaryotes have a nucleus and other organelles as well as a exoskeleton of microscopic protein fibers. (Click Here For Video!) f. The lipid Bilayer of a cell membrane is made of a double layer of phospholipid molecules. g. Proteins in cell membranes include enzymes, receptor proteins, transport proteins, and cell surface markers. 3. Students will be able to summarize and describe the characteristics of a cells organelles. (Click Here For Video!) a. The nucleus of a eukaryote directs the cells activities and stores DNA. (Click Here For Video!) b. In eukaryotes, an internal membrane system produces, packages and distributes proteins. (Click Here For Video!) c. Mitochondria harvest energy from organic compounds to ATP. (Click Here For Video!) d. Lysosomes digest and recycle a cell’s used components. (Click Here For Video!) e. Plant cells have structures that animal cells lack: a cell wall, chloroplasts and a central vacuole. (Click Here For Video!)
